i y for reissue filed June 4,

ToaZZ whom it may concern Be it known that I, WALTER a citizen of the United States, residing at St. Louis, Mi'ouri, have invented a certain new and useful Improvement in Tire Locks, of which the following is a full, clear, and exact description, such as will. enable others skilled in the art to which it appertains to make and use the same.

This invention relatesto locks for lockng Vspare tires carried on motor vehicles., ne object of the invention isto. provide a lock for the purpose mentioned which is so constructed that it is practically impossible to break or cut the lock or the strap which engages the tire, and in which the lock is so constructed that it is impossible to insert a tool or implement to cut or tamper with the lock or the lock bolt.

Another object is to provide a spare tire lock for vehicles in which the means thatl surrounds the tire and the tire carrier on the vehicle is .so mounted that Athe vibration of thevehicle will not cause said means to chafe or cut the tire or rattle'againstthe tire carrier.

And still another object of my invention is to provide a spare tire lock for vehicles comprising a means that surrounds or embraces the tire and the tire carrier on'the vehicle, and a resilient element or ldevice combined with said means in such a manner that it serves as a resilient backing for said means which permits said means toyield in the event an attempt is made to cut said -means with a chisel or other cutting tool.

IWith the foregoing and ther/ objects in view, I have produced an efficient embodiment of theinvention, "one form of 'which` is illustrated in theaccompanying drawing, I

T. CAMPBELL,

Figure 1'is a plan view 'of the lock. 'n Figure"2 is a side or end elevation ofthe lock in service. v

F"gure`3`is. a sectional view of the lockl ease,- showing the lockng,mechan1sm, and 'the manner in which the'lock Ibolt engages the tire engaging strap or band. l'

Myinvention comprises a flexible strapor band 1 which is preferably of lvery hard material, such, for instance, as alloy steel, so that it is impoiible to out or to break the band or strap. The inventlon comprlses Specication of Reissu upon the strap ed Letters Patent Reissued May 30, 1922.

the band or strap around the tire.

As shown, the lock comprises a case com# posed, p-referably, of a casting or block of metal comprising a. base 2, aI portion 3 rising from the base and arranged, to contain the lock bolt, and a portion 4 arranged to conltgailn the mechanism` controllingV ther-lock The base Q of the lock case is provided with an arcuate or curved passage 5 therethrough, designed and adapted to receive the ends of the tire engaging band or strap 1-. The extremities of the band or strap 1 are curved tov the contour of the pasge 5, and one end of the band or strap is secured or attached to the base 2 of the lock case. As shown, the end which is permanently secured to the lock case is held by rivets 6 which permit the other end of the strap or band to be inserted into andremoved from the-passage 5 when the lock bolt is disengaged there-from. Y The base of the lock shoulder 7 at each case has an .extended side, which shoulders project beyond the lower portion ofthe base. This construction is important, in that the shoulders function to prevent the application of an cutting tool upon the strap 1 immediate y 'above the ends of the base 2 of the lock case. For the reasons hereinafter described, it will be seen that if a cutting tool or other implement is placed 1, the shoulders 7 hold such tool above yie ding rtions of the resilient strap; with the resu t that when the cutting tool 'is struck b a hammer the resilienc of the strap willy throw the cu-ttin tool o and this w1ll occur without materia-l injury' to the strap, due-1 to the very hard nature thereof.` 5 l l The upper wall of the passage 5, which is the concave wallA of.- said paage, is formedV 'with a number of `shoulders or projections 8. These shoulders or projections 8 function. to prevent the insertion of any tool or implement into the passage 5, thus preventing tampering with the lock bolt.

It is apparent that if 1t be attempted to insert a chisel orlike implement into the passage 5, such chisel or implement .w1ll be obstructedV by the shoulders or prpjectlons for locking the same I 8 and prevented from being driven into contact with the lock bolt.

further, a novel lockingdevice for engaging The extended portion 3 nf the 100k case is "110 formed with a chamber in which the lock bolt 10 is operatively located. 'Ehe end of the chamber 9 is closed by a closurell in the form of a hollow plug which is screwedj into the chamber 9 and locked in position by a pin 12 driven into an opening formed by matching grooves in the wall of the closure 11 and in the adjacent portion of the lock case. The outer'ends of the closure 1l and the lock pin 12 are flush with the surface of the lockkk case, so that said elements can not be engaged by any tool for the pur-A pose of removing them.

The lock bolt 10 is actuatedtoward locking position by a spring 13 of the expansion type. The spring 13 is seated within the recess in the closure .11 and has its inner end encirclin` a projection 14; on the lock bolt, thereby olding said apparatus properly centered;

The end of the strap 1 which is attached permanently to the lock case has a hole therethrough in alignment with the `chainber 9, so that the lock bolt 10 may be moved to and from locking position. 7When in locking position, the lock bolt 10 Vextends through the Vregistering holes in the over-` lapping ends of the strap 1 and into a recess forming the continuation of the chamber 9 in the base of the lock case. In order that the strap 1 may-,be fitted around tires of different sizes,"the detachable end of said strap is preferably formed with a number of holes therethrough, through one of 'which the lock bolt may be passed as determined by the size of the tire, encircled by the strap.

` The flock bolt is movable from locking position by an arm or lever 15 engaging in an appropriate notch or recess 16 in the lock bolt. The arm or lever 15 is in connection,

- with the barrel 17 of the locking mechanism. i

The locking`fmechanism may be of any appropriate construction that will function to lock the barrel in position to hold .the arm or lever`15 `in its lowered position, thus, locking thev lock bolt 10 in the vposition shown in Figure 3.- The lock is preferably of any known type adapted to be operated by. a key and to permit removal of the key when the barrel of the lock' is in position to hold the arm 15 in its lowered position.

A closure or guard 18 for the key hole i may be "provided, the saine comprising a ven pivotally .supported disk movable to and 'from position to close the key-hole, and

preferably having a projection 19 for man` ual engagement.

The Jlock is -preferably provided with a resilient element or device that performs two functions; to wit, it preventsthe means that surrounds the tire and the tire support-` ing device on the vehicle from cutting `or chafing the tire or rattling on said tire supporting device, and it forms a resilient back-` ing for said means which permits said herein illustrated the resilient element or device just referredV to consists of ay leaf spring 20 secured to the underside of the base of the lock case in such a way that it will bear against the tire carrier supporting device 21 on the vehicle, and thus be held in tension when the band 1 is drawn around the tire and the tire carrier and locked" in position by the concealed key-controlled llocking means in the lock oase.

From the foregoing, it will be seen that I have provided a lock which is practically Aindestructible and incapable of injury by the usual means used for breaking locks. Due to the peculiar and novel construction of the co-operating parts, it islimpossible to open the lock by tampering therewith, so that the lock can not"be opened without the use of the proper key. The provision of the arcuate passage 5 with the shoulders 7 at the ends thereof and the projections 8 on the concave wall thereof makes it impossible either to cut or break the strap 1, or to insert a'tool into the lock to release the lock bolt. Then `the lock is provided with a resilient device interposed between the tire carrier on the vehicle and the portion of the lock that surrounds the tire and tire carrier, it is impossible for said portion to cut or cha-fe the tire, rattle against the tire carrier or be cut by a blow or pressure applied to said portion.V y

I do vnot restrict myself to unessential details or features of construction, since it is apparent that variations may bel made in the construction and arrangement of the" lock without departure fromA the nature and principle of the invention.
